生物活性/药理作用

In mammalian systems, β-hydroxybutyrate dehydrogenase is localized on the inner mitochondrial membrane and requires phosphatidyl choline for activity. In contrast, the enzyme from Rhodopseudomonas is a soluble cytosolic enzyme that does not require a phospholipid allosteric activator. The enzyme is required for the utilization of ketone bodies as a source of metabolic energy. It catalyzes the oxidation of 3-hydroxybutyrate to acetoacetate, the first step in the conversion of ketone bodies to citric acid, which is then further metabolized via the  tricarboxylic acid cycle (Krebs cycle).

应 用

Suitable for the determination of acetoacetate and D(-)-3-hydroxybutyrate by the method of Williamson, D. H., and Mellanby, J., Methods of Enzymatic Analysis, Bergmeyer, H., ed., 2nd edition, 4, 1836 (1974).

有效单位定义

One unit will oxidize 1.0 μmole of D-β-hydroxybutyrate to acetoacetate per min at pH 7.8 at 37 °C.
